Answer:
This equation has 2 solutions.
1. ![x=\frac{-15+\sqrt{89}}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-15%2B%5Csqrt%7B89%7D%7D%7B8%7D)
2. ![x=-\frac{15+\sqrt{89}}{8}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B15%2B%5Csqrt%7B89%7D%7D%7B8%7D)
8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
Answer:
There are 2 ways, since we'd chosen 2 fruits
PROBABILITY:
(
=
) or ![\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D)
METHOD:
In the 2 fruits we took both of them might be pears either maybe one of them can be a pear. The same is possible with the other fruit.

Answer:
Very last choice is the answer.
Step-by-step explanation:
Remark
The thing that is most important is that the horizontal line connect h and the radius is parallel to the cut of the sphere if it was placed right in the middle. That line swings around as though the center was a pivot.
Solution
- So what you have is a circle when that line goes around that part of the sphere.
- To find the length of that line, use the Pythagorean Theorem. Call the line r1.
- r1 ^2 = r^2 - h^2
- So the area is pi * r1^2
- Area = pi (r^2 - h^2)
- The very last one is the answer.
